“…Deep water fisheries in Latin America focus mainly on benthic and demersal invertebrates (Arana et al 2009;Wehrtmann et al 2012). Detailed information on the composition of shrimp bottom-trawl fisheries' catch in the region is limited to the Chilean nylon shrimp fishery (Heterocarpus reedi Bahamonde, 1955), and the northern nylon shrimp (Heterocarpus vicarius Faxon, 1893) and kolibri shrimp (Solenocera agassizii Faxon, 1893) in Central America and Colombia (Chile: Queirolo et al 2011;Arana et al 2013, Colombia: Puentes et al 2007, Costa Rica: Wehrtmann and Echeverría-Sáenz 2007Arana et al 2013;Villalobos-Rojas et al 2017). Nevertheless, little attention has been paid to hermit crabs caught as bycatch in these fisheries.…”

“…Few studies assessing the fauna associated to bottom-trawl shrimp fisheries have considered its impacts on small and non-dominant species (< 0.1% of total catch) (Branco et al 2015;Villalobos-Rojas et al 2017). In fact, hermit crabs have been rarely identified when monitoring the bycatch present in shrimp bottom-trawl fisheries (Branco et al 2015;Gimenez-Hurtado et al 2016).…”

“…), but the otter trawl is currently the most important commercial gear worldwide (Gillett 2008). In recent decades, the concern over the bycatch of the shrimp trawling fisheries has increased significantly (Dumont and D'Incao 2011;Queirolo et al 2011;Meltzer et al 2012;Arana et al 2013;Villalobos-Rojas et al 2017;Clarke et al 2018), and the discard rates of these fisheries has MARINE AND FISHERY SCIENCES 33 (1): 95-113 (2020). https://doi.org/10.47193/mafis.3312020061806…”

Studies of the bycatch associated to the shrimp trawling fishery in the Pacific coast of Costa Rica do not assess small organisms (< 10 cm TL) and non-dominant species (< 0.1% of total catch). There is a void in assessing the maintenance of the ecology and ecosystem on which the fishery depends. Furthermore, the Constitutional Court of Costa Rica prohibited the renewal of existing and the issuing of new shrimp bottom-trawl licenses, indicating the necessity of more scientific information on the impacts of this fishery. We present the results of a 23-month study of the shrimp bottom-trawl fishery performed between 50 and 350 m deep in the Pacific coast of Costa Rica. A total of 109 hermit crabs were collected (six species and two families). Paguristes cf. holmesi was the most common species. Zone II presented the highest species richness and abundance. Most specimens (81.8 %) were caught in shallower waters (50-149 m). More than 45% of the trawls presented hermit crabs. It is imperative to further assess the trawling effects on non-commercial benthic fauna and changes on predator-prey relationships before issuing new shrimp licenses

“…Jorge Campos and his collaborators from CIMAR published in the 1980s on fishery-related aspects (e.g., Campos, 1983), and Ingo S. Wehrtmann has been publishing about this topic in the last decade. One milestone for this research topic was the foundation of the Unidad de Investigación Pesquera y Acuicultura (UNIP) of the CIMAR in September 2007, which has generated numerous projects and publications, especially regarding deepwater bottom-trawl shrimp fishery and its bycatch (e.g., Wehrtmann & Nielsen-Muñoz, 2009;Clarke, Espinoza, Ahrens, & Wehrtmann, 2016;Villalobos-Rojas, Azofeifa-Solano, Camacho-García, & Wehrtmann, 2017).…”

Bibliometrics play a significant role in evaluating the scientific production of journals and research units such as universities and research centers. The present study aimed to analyze the scientific production of CIMAR (Center for Research in Marine Science and Limnology) from its foundation in 1979 to 2015. We analyzed exclusively articles published in journals and selected those with at least one author affiliated to CIMAR. For the analysis, each article was classified according to the geographical study area, the topic of the investigation, ecosystem, and taxonomic group. We analyzed the following variables: year of publication, language, journal name, and authors. In this study, we analyzed the Bradford distribution, citations, the impact factor, and the quartiles of the journals where papers were published. During the study period, CIMAR produced a total of 791 publications: 624 articles, 90 book chapters or books, 48 booklets, and 34 special issues of the journal Revista de Biología Tropical (RBT). The number of publications showed an increasing trend during the study period, and most articles were written in English (58.3 %) and Spanish (41.7 %). A total of 128 journals were selected to publish CIMAR’s contributions. According to the Bradford method, the journal RBT is in Zone I (major productivity or concentration), with 49.8 % of the total scientific production. In relation to authorship, 22 authors with 12 articles or more are registered, and 80 % of the articles have been published by authors with a low (42 authors) and medium productivity level (44 authors). CIMAR published 81.6 % regarding marine topics and 18.4 % about limnology. Most of the articles (51.9 %) dealt with the Pacific of Costa Rica, 13.5 % with the Caribbean and 34.7 % referred to other study locations. The publications of CIMAR were mainly about ecology (33.3 %), taxonomy (24.5 %) and oceanography/meteorology (12.7 %). CIMAR has a highly trained and specialized staff that has gained experience and is contributing to the implementation and evaluation of Costa Rica’s science, technology and innovation policies through both interdisciplinary research and the development of institutional as well as professional capacities in a framework of dialogue and public-private agreements.
